PortfolioGPT
Pros
- + Risk-tolerance input materially changes the output mix in matched-pair tests — aggressive runs tilt to equities and crypto, conservative runs to bonds and ETFs
- + Free tier with five generations a day is enough to run a full scenario matrix before paying anything
- + Outputs include dollar allocations at your stated principal plus horizon-matched backtested figures, not just ticker lists
- + Cheapest serious entry in the category: $3/month or $27/year per the vendor's own pricing pages
- + Sibling tools (Index GPT, Sector GPT, Real Estate GPT) extend the same workflow to index, sector and property portfolios
Cons
- - The goal field has no effect on output — the vendor's own docs admit it, and matched-pair tests confirm it is a placebo control
- - No per-pick rationale, no benchmark or fee assumptions on backtests, and no methodology document anywhere on the site
- - Cannot edit a generated portfolio — no way to swap out an individual holding you disagree with
- - No trade execution, brokerage connections, rebalancing or tax-loss harvesting; purely an ideas generator
- - Thin maturity signals: self-contradictory homepage counters (1,640+ portfolios vs 2,160+ investors), no visible support organization, sparse independent coverage
Mercury
Pros
- + Base plan is genuinely $0/month with no minimums or overdraft fees, and the free surface covers checking, cards, invoicing and bill pay
- + Insights — live dashboards, ad-hoc financial questions, spend notifications — is included free on every plan per mercury.com/insights
- + Command executes natural-language instructions across the account stack but only with explicit per-action approval and a traceable record
- + Up to $5M FDIC insurance through partner banks and sweep networks, per the plan comparison
- + Free API, MCP server and CLI let you drive Mercury from your own agent tooling
Cons
- - US-only for business banking, cards and treasury — non-US entities are excluded
- - Treasury requires a $250K Mercury balance to unlock, locking out early-stage startups
- - AI features only see Mercury data; no connection to external revenue or payroll systems unless routed through Mercury
- - Enriched NetSuite automations and $0 ACH debit invoicing sit behind the $299/month Pro plan
- - 1099 filings cost $5 per filing on the free plan, and Books/Payroll are add-ons whose fee waivers end 31 December 2026
